WARE-THREAD PLATE.

1 Application led April 21, 1924. Serial No. 708,046.

To all -zcwm z't may concern.'

Be it known that I, HERBERT V. W. SCOTT, a citizen of the United States,residing at Paterson, in the county of Passaic and State 5 of NewJersey, have invented certain new and useful Improve-ments inWarp-Thread Plates, of which the following is a specilication.

My invention relates to warp thread plates for textile machines; and isnot only used for threading-in a warp, but in many cases the. threadscontinue to run through the plate after both the warp and the plate areplaced in the machine. It is not only used in jacquard machines, but isalso used for making of warps in any textile 'machine Where a Warp isused, as for instance, in warp knitting machines, broad silk looms,carpet looms, etc., etc.

In textile warping, the yarn is lirst wound on spools, and a largenumber of these spools are placed on a jack or creel.' The ends of thethreads from these spools are threaded through the holes of the warpthread plate which is placed directly in front of the warping mill. Thenas the threads are run through the plate onto the mill, they are gaugedby the lay-out of the plate holes to conform with the machine uge orcloth 30 count desired. Hence the p ates vary in shape according to themachine with which they are to be used and the number of threads perinch desired. The plate shown in the drawings has 168 holes laid out insix rows on a four inch plate; others might have an equal number ofholes laid out in four rows on a six inch plate; while others might havea total of, say, only 80 holes, etc.

The object in view is to provide a plate that will prevent the yarn frombeing cut by any rough edge or surface. I have found out by experiencethat silk running at a high speed through holes in a metal plate willcut the metal regardless of its hardness and the grooves andirregularities thus formed, will in turn, abrade and cut the threads.

`Minor obj eets of the invention will appear in the subjoineddescription. v The inventionconsists in the construction and arrangementof the parts, and the method of assembling the same and,

' e them in rigid relation to each other', as wi be hereinafterdescribed and claimed, refer-- section, on an enlarged scale, showingone y form of eyelet or bushing'as it appears em-' bedded in the plate.

The numeral l indicates the plate,l which is provided with aplurality/ofsuitably arranged holes 2; and these holes are provided 1nturn with eyelets or bushings 3 to take up the wear. A

I have found in practice that porcelain is an admirable material to usein making these bushings, because of its great smoothness andgreatresistance to wear; but I do not limit myself to the use of any onematerial, either hard or soft, for these eyelets or bushings, usingwhatever material may be found most desirable to meet any given' case,since my device is not limited to the silk industry, but as alreadystatedis used wlth any textile machine whatsoever where warps are used.

The eyelets are secured in the plate in any ordinary or preferredmanner. In practice I have found that mould casting is usuallysatisfactory. The small eyelets are placed on plus inside the mould, andthe molten instal, or alloy, poured in.

'I hese eyelets or bushings are made in any deslred form, thatillustrated in Fig. 2 of the drawings 'being a good form. In this formthe eyelet is provided exteriorly with an annular swell 3a, so that whenthe molten metal hardens around it, the eyelet will be soy very firmlyheld in the plate, which is comparatively thin.

Whenever itis deemed necessary to do so, a little antimony may be addedto the metal or alloy (from which the plate is more' often made), tocause the metal as it cools to contract around the eyelets, and in thatway grip them very t' htly.

The addition olthe l gives it great stren h for its size.-

To those skilled gd the art,

parent, since inan al1-metal plate, however l los y porcelain plate isvery brittle, and e'onse'- quently easily broken; but with myarrangement any suitable material, either metallic or non-metallic, maybe used for the plate.

Having now described my invention, what I claim as new and desire toprotect by Letters Patent is l. In a device of the character described,a plate formed from molten metal by casting, and having wear eyeletspreviously formed of a different material, said eyelets being arrangedin position conforming to the configuration of the plate to be formed,

1 and cast in the plate simultaneously with its formation, the moltenmetal being poured around them; whereby the complete eyelet plate isformed at a single operation, and the plate and eyelets are from apractical point of View integral in formation.

2. In a device of the character described, a plate formed from moltenmetal by casting, and having wear eyelets previously formed of adifferent material, said eyelets being arranged in position conformingto 'the configuration of the plate to be made, and cast in the platesimultaneously with its formation, the molten metal lbeing poured aroundthem; whereby the complete.

eyelet plate is formed at a single operation,

the eyelets beingy arranged between the planes formed by the oppositesides of the plate, whereby not to project beyond said planes.

3. In a device of the character described, a plate formed from moltenmetal by casting, and having wear eyelets previously formed ofporcelain, said eyelets being arranged in position to conform to theconfiguration of the plate to be formed, and cast in the platesimultaneously with its formation, the molten metal being poured aroundthem in the plate, whereby to# utilize the shrinkage of the metal incooling to rigidly secure the eyelets in the plate without the use ofcement, the eyelets being of a length equal to the thickness of theplate with their open ends ush with the sides of the plate; whereby toprovide a' plate of practically integral construction withoutprojections on either of its faces.

4. In a device of the character described, the combination with a platehaving openings therein for the threads, of bushings cast in saidopenings, said bushings being exteriorly provided with annular swells.

In testimony whereof I aiix my signature.

HERBERT V. W. SCOTT.
